One of the biggest Pyralids about is the Mother of Pearl below. It may reach a wingspan of almost 40 mm! A dreadful species to beginners to identify, for it really does look like a Geometer at first. It is a micro moth, but considering the size, most people will search among the macro moths in their books or on the web. A very common species in the south of Britain, where it often flies about in very great numbers. Widespread but more local and flying in smaller numbers going northwards. More about the Mother of Pearl in the near future.
